Dalton Natural Gas Pipeline Extension

Dalton Natural Gas Pipeline Extension

Newnan, Georgia to Dalton, Georgia–2014 to 2015

Services: Geotechnical
Clients: Laney Directional Drilling Company

Project Detail

Geo-Hydro performed a geotechnical subsurface investigation for the construction of 109-mile natural gas pipeline route extending from Newnan to Dalton, Georgia. The pipeline has a diameter of 30 inches at its inception point in Newnan. Between Newnan and Dalton, the diameter of the pipeline decreases twice: once to 24 inches and then to 20 inches. Construction of the pipeline required multiple road, river, and stream crossings. Geo-Hydro’s subsurface exploration assessed nine of these crossings at which the use of horizontal directional drilling was proposed. Drilling sites in Paulding County were located near Pumpkinvine Creek at Georgia Highway 120, Amanda drive near Marshall Fuller Road, and Braswell Mountain and High Shoals Roads west of Georgia Highway 61.  The scope of geotechnical services entailed soil test boring and rock coring to depths ranging from 100 to 160 feet, laboratory testing for soil classification including corrosion potential, and unconfined compressive strength testing of rock. Geo-Hydro provided its work under contract to Laney Directional Drilling Company.
